Next Service request and there is a relay configure with credentials Interested in MRAS, here we have a relay configured. Shows different sip dialogs and left SIP header and on the right the detailsįirst incoming 200 OK – in band provisioning SfB Online using Media relay or Lync 2010, Lync 2010 always uses media relay Sign into service, from signalling learn a relay configured for me candidate promotion selects best media path candidate exchange and try to establish connectionĥ. candidate discovery – once i know where i can be reached i send to clientģ. based on endpoint location and privacy boundariesīased on ECMP and how can easily distribute loadĢ.and closest servers is always used with least hops.Transport Relay in progress with SfB but is in use with Teams Transport relays uses different UDP port per workloads.View the other two ignite sessions as well Important for local internet connections as you may not be able to take advantages of the transport relay and keep traffic local. Travel to orlando i can use transport relay in the US not Europe. Transport Relays – much smarter and uses dynamic discovery via anycast Media relay static in one DC, if your in Orlando and media relay in Europe traffic travels back to Europe to use the relay. Transport relay built for scales and more flexibility

Media relay component built for Skype for business server and was the edge server and was moved to the cloud but wasn’t built for the cloud so a cloud solution was born

Teams we upload files to OneDrive for Business.

client sends packet to relay servers and allocates candidates and sends back packet and knows my public ip is this and then client knows this is my public ip and maybe i can accept traffic there.

also same time helps us find our public ip address and will allows net to allow incoming traffic.

Now we have STUN and TURN server these are servers and function as a relay if client wants to talk to someone but cant it can use stun and turn server as relays.

For Teams is not SIP its REST API via https and web sockets for more persistent comms no more sip.

real time may not be real time if any latency addedįirst there’s signalling that goes via the Cloud.

Bad for Teams and SfB as doesn’t allow UDP only HTTP will always use TCP.

Additional features, deep packet inspections and proxies.

Great as it provides security as well as unknown traffic to your ip would get dropped is not requested. Now we need some logic that helps to establish all the different call flowsĮxample at home you can have lots of different devices, Xbox’s, PlayStations, pcs with internal ip address all sharing a single public ip address. Then theres Charlie’s, outside the network as wellįirewalls also may not allows direct communication from external clients on internet to internal clients. They have devices that don’t allow direct calls.this is a problem. If they want a call we want to send as direct as possible, they could be in same site or same office or across floor but the network is directly routable. two types of relays., media relay and transport relay.įirst they need Signalling to say “Hey I’m here”Ĭall could be audio, video or desktop sharing ICE – uses two techniques, STUN and help to transverse a net device, TURN – relay technique. Not taking about signalling, its all about mediaĬandidate is combination of IP and port and allow other peer to connect

stress UDP ports 3478, 3479 these are critical.

great to have local internet breakout and not all traffic to central locations,.

Thank you Thomas for this great session! there was a lot of applause at the end and well deserved!ĭone this session a couple of times for SfB before and opens questions the audience

Hot TIP with teams logs towards the bottom of the highlighted Yellow is how to format Teams logs to noted with line breaks “ \r\n this is line break so replace with “ “ Towards the end great tips on tools to use to read logs and traffic and troubleshooting. Its amazing just how much happens under the hood that users never see just how SfB and Teams finds the best media path, codecs to set up and have a best quality call possible with client connected everywhere. Great session by Thomas Binder and there’s a ton of awesome information and tips on media flows and understand media / transports relays and the difference between Skype for Business and Teams. Following ignite there’s a ton and awesome content and session recordings to watch so this today i saw Thomas Binders session on “Understanding Media Flows in Microsoft Teams and Skype for Business” and thought this should be a goodie.
